Rescue crews are searching for a 31-year-old man who fell into the Colorado River near the State Bridge area, in Eagle County, this morning after the sheriff’s office received a call from someone who heard that a man had fallen in, police say.

Eagle County police know the man is from the Denver area but have not identified him, said sheriff’s office spokeswoman Shannon Cordingly. She said alcohol may have been a factor in the incident.

Cordingly said police received an emergency call just before 10 a.m., about an hour to an hour and a half after the man fell in the river.

Crews from Eagle fire protection and ambulance, Vail Mountain Rescue and the Gypsum Fire Protection District have joined the sheriff’s office in searching the river banks on foot.

In addition, a helicopter from TriState Care Flight is searching the river three miles to five miles from the man’s last known location.
